SOLUTION: Find the slope of the line 3x - 5y=15. What is the y-intercept? Solve:{2x-3y=5 {6x-9y=10

Question 200493: Find the slope of the line 3x - 5y=15. What is the y-intercept?
Solve:{2x-3y=5
{6x-9y=10

A) 3x-5y =15
-5y = -3x +15
divide by (-5)
y = (3/5)x -3
.
slope is (3/5),,,,,,y intercept is (-3)
.
B)
1) 2x-3y =0
-3y =-2x
y= (2/3) x
.
2) 6x -9y =10
-9y = -6x +10
y= (6/9) x +10
y = (2/3)x +10
.
These lines are parallel, slope (2/3),,,,therefore no solution
.
aside, if we solve math we reach something like 0=10, which is " never true" , and this leads to " no solution" also
